Quizplus · Accepted Answer

A derived attribute is an attribute that can be calculated or derived from other attributes. It does not physically exist in the database, but it is obtained by applying a formula or a function to other attributes. Therefore, the value of a derived attribute is dependent on the values of other attributes in the same entity or related entities.
